A company implements a new process to manufacture its product and uses 100 hours to complete one unit. It expects that the new process will be subject to an 80% learning curve. If the company assumes the learning curve will follow the cumulative average-time learning model, how many total hours will be needed to complete four batches? 64 hours 400 hours 204.8 hours 256 hours A company has accumulated data for the last 24 months in order to determine if there is an independent variable that could be used to estimate shipping costs. Three possible independent variables being considered are packages shipped, miles shipped, and pounds shipped. The quantitative technique that should be used to determine whether any of these independent variables might provide a good estimate for shipping costs is: variable costing. high-low method. linear regression. expected value. In order to determine how its in-house training program is affecting its employees' performance rating, Maxis Tech performed a regression analysis with the following results: Performance rating =0.2+0.05 hours of training R-squred =0.1 Given the above information, Maxis Tech can conclude that: The company should explore factors other than number of training hours received that might better explain an employee's performance rating. The number of training hours received has a significant impact on an employee's performance rating. An employee's performance rating will be 0.35 if the employee receives only one hour of training. For every hour of training received, an employee's performance rating will decrease by 0.05
